The First Master and the founder of the Fairy Tail Guild. She is also referred to as the mother of Fairy Tail. In year X686, Mavis, along with Precht, Warrod Sequen and Yury Dreyar, founded the Fairy Tail guild, with Mavis being the guild master. As they finally finished the guild building, all four took a photo with the building in background as a sign that Fairy Tail was born. She later entrusted the guild to Precht to serve as its second master. In gratitude, members of Fairy Tail made her a grave on the holy island of the guild - Tenrou Island. Mavis was given with an epithet as the Fairy Tactician, since she led her team in many victories thanks to her exceptional skills in making strategies during battles.
Shortly before founding the guild, Mavis' body becomes unable to grow nor mature after she uses Fairy Law in an incomplete stage, when her body could not withstand the burden of the magic.
